Lightmatter
A first-person puzzler where only the light is safe
First Impressions
I treat Lightmatter as a reading of its Steam reviews, not as my own playthrough. Developed by Tunnel Vision Games and published by Aspyr in 2020, this first-person puzzler sits at a steady figure: as of 2026-06-29 the label is Very Positive, with 93% of 679 Steam-purchaser reviews positive and about 91% across all 2,894. The critic aggregate (Metacritic 73) runs a touch cooler than the players.
Line up the helpful positives and the praise converges on three things: the clarity of 'touch a shadow and you die,' puzzles that are 'smarter than they look' built from just lamps and pylons, and the voice of CEO Virgil (David Bateson, of Agent 47 fame). Many write 'I've never played a puzzle like this.' The qualified positives and negatives keep returning to 'short (2-3 hours),' 'pricey at full price, buy it on sale,' and 'it can't step out of Portal's shadow.'
What interests me is that praise and complaint point at the same thing again. One reader's 'full of love for Portal' is another's 'just a Portal imitation.' I read that not as a fight but as a question of where the design splits, and who it is aimed at.

Putting the Mechanics into Words
Nearly every positive names one rule: touch a shadow and you die instantly; only the light is safe. The player's verb is effectively one - place light, or bend it. There are only two tools: a portable lamp you set on the floor, and a pylon (photon connector) that relays a beam as long as it can see a source. The shadows cast by ceiling fans and conveyors turn into blades, and dodging them is the board. It's 'the floor is lava' translated into light and shadow - an inverted grammar of safe ground.
The tip every reviewer repeats is 'think in reverse.' Decide where you want light to end up, then work backward to where the sources go. That is grammar in the Puzzlebyrinth sense: pulling the picture of a solution out of a few tools, backward. Once the two verbs - lamp and pylon - start to cross, a combinatorial explosion grows from a tiny set. Few verbs turning into depth is the first-person puzzler's well-worn road.
Light, shadow and beam belong to the same lineage as The Turing Test and The Entropy Centre, building each room as a self-contained lab. The near-total lack of moving physics (the 'no physics' note in reviews) reads to me not as a gap but as subtraction that keeps light predictable. The fewer things move, the more a player's attention narrows to the edge of the light.

Place in the Lineage
It's safe to say no review of this game leaves out the name Portal. The store page itself flies the banner 'a love letter to first-person puzzlers,' and the game is dotted with nods to Aperture and the cake. The positives welcome this as 'love' and 'a treat if you know the source'; the negatives write 'it's like being told REMEMBER PORTAL? on repeat' and 'it can't leave its most brilliant predecessor's shadow.' Slant's review needles that complaint - a game about shadows, swallowed by one.
I read this as a question of position, not rank. Lightmatter's originality is not Virgil or the story but the single paired verb of light and shadow. When reviewers say 'I've never played a puzzle like this,' they mean the verb newly poured into the frame, not the borrowed frame itself. Own contents in a borrowed vessel - how you count that mix is what makes the same game look like 'love' or 'imitation.'
For the lineage, Superliminal, which makes perception itself a verb, and The Witness, which makes observation the lead, are the rooms next door. Lightmatter invents less of a framework than either, but it polishes the single move of 'placing light' inside an existing one. Invention and refinement are different axes; reviews split most when people try to measure both with one ruler.

The Feel of the Story
Alongside the puzzles, the lead of the reviews is the narration of Virgil, the facility's CEO. The positives call David Bateson's voice (of Agent 47) 'the highlight' and 'a villain with real presence.' You play a memory-wiped, unnamed figure escaping a shadow-infested facility on Virgil's caustic directions. Many reviewers name the performance - comic venom sliding into late-game unease - as the game's top strength.
On the other side, 'a GLaDOS retread' and 'a story told out of order, hard to follow' recur. The late twists about your identity, and the goal sliding from escape to shutdown, read to the negatives as 'motives so vague the character is just a vehicle for puzzles.' One helpful review notes the finale strains for tension but mostly has you die and respawn with a shrug.
I read Virgil's narration as story and a teaching layer at once. His quips quietly trail the next room's tool and raise your observational resolution when you stall. Expect a thick story and it feels thin; take it as a puzzle companion and it's just right - the split, again, comes down to what you count as the main thing.

The Texture of Difficulty
Difficulty is the other axis where reviews split. Some write 'it builds ease carefully' and 'it twists your head just enough,' and voices like TechRaptor call the 'Aha moments brilliant.' Others - Slant among them - write that the real Aha moments are few, that the difficulty stops in a dissatisfying middle, and that the game ends before it tests you. The same difficulty reads as 'just right' to one player and 'not enough' to another.
Collect where people get stuck and it sorts qualitatively. The first half teaches only lamps, the second only pylons, and you combine both only at the very end - a structure several reviews call a 'strange split.' Teaching one tool at a time makes for a gentle learning curve, but it holds back the combinatorial explosion of the two verbs until last. Most of the hard spots cluster late, because the merge arrives late.
And almost everyone mentions that the final stage suddenly turns from puzzle into a parkour-ish platformer. Reviews split cleanly between 'a nice change of pace' and 'out of place, doesn't fit.' The texture of difficulty shifts from reading the puzzle to precision of control - less a flaw than the designer choosing a different tension for the curtain. Best read as a question of who it's aimed at.

Sources
This piece was written by reading the user reviews on the Steam store page as of 2026-06-29. No review text is quoted directly; typical claims are reconstructed.
- Steam: Lightmatter (Very Positive; 93% of 679 Steam-purchaser reviews, ~91% across all 2,894, 94% of 18 in the last 30 days)
- Read via WebFetch: the top helpful positives, representative qualified and negative complaints, and several recent reviews
- Reference: critic tone via Slant Magazine and TechRaptor; aggregate cross-checked on Metacritic (73)
Closing
Steam's overall is 93% (679 Steam-purchaser reviews, 2026-06-29), the critic aggregate 73. I give it 7.5 on design grounds. Running cooler than the players tracks the recurring notes on its short length, its closeness to Portal, and the late merge of its two verbs - not a reservation about the central move of placing light.
Lightmatter does not reinvent an existing frame. But the review numbers show clearly that it polishes the single paired verb of light and shadow into boards smarter than they look. For those who enjoy Virgil as a puzzle companion, or want the pleasure of reverse-engineering in a short, dense dose, it reads 'short but sharp'; for those after invention itself, 'a well-made imitation.'
If bending light into a path appeals, The Witness and The Entropy Centre are the rooms next door. The first hour is free to try, so siding with the majority and waiting for a sale rather than full price before you step into the light is fair.

The Lost Vikings (1993) — A Classic of Cooperative Puzzling, Three Bodies Moved One at a Time
Released in 1993 by Silicon & Synapse (later Blizzard Entertainment) through Interplay, The Lost Vikings is a cooperative puzzle in which the player controls three differently-skilled vikings one at a time and must lead all of them to the exit. In Japan it was distributed by T&E Soft under the title Viking no Daimeiwaku. This essay re-reads its era, the quality of thought its three-way cooperation produced, and the lineage that runs from Lemmings and Gobliiins to today's cooperative puzzles.
